The invention discloses a selective breeding method for a long-grain, fragrant, disease-resistant and high-quality black rice three-line sterile line, and belongs to the technical field of special rice breeding. A black rice variety A with the high anthocyanin content, a rice variety B containing Pigm rice-blast-resistance genes, a long-grain, large-grain, fragrant and low-amylose-content rice variety C and a common cytoplasmic male sterility maintainer line variety D with the good combining ability serve as a parent, and through technologies such as hybridization, composite cross, pedigree method selective breeding and character identification, excellent character polymerization is achieved, and the long-thin-rice-grain, fragrant, disease-resistant and high-quality cytoplasmic male blackrice sterile line is finally selectively bred. The sterile line is used for preparing strong advantage specificity three-line high-quality black-rice hybrid rice, the appearance quality of black ricecan be improved, and the requirements for long-thin-rice-grain, fragrant and high-quality black rice products on the market are met.
